106 ;;Quote: the Internet connected the ARPANET with the ARPA packet radio network using packet switched gateways

106+;;Quote: the Internet is a packet switched communications facility; a network of networks connected by gateways using store and forward packet forwarding

107 ;;Quote: the Internet integrates separately administrated networks into a common utility

107 ;;Quote: the ordering of goals for the Internet is important: survivability, multiple types of services, ..., accountability

107+;;Quote: Internet designed for military survivability and not for accountability; accountability not needed in wartime

108 ;;Quote: except for total partition, the Internet masks all transient failures; must protect the state about an on-going conversation

108+;;Quote: fate-sharing--can loss state about an entity only if lose the entity itself; e.g., store synchronization information with the hosts and not the gateways, trust the host instead of the network

109 ;;Quote: the Internet separates TCP from IP to allow other transports that optimize delay or bandwidth instead of reliability

109+;;Quote: TCP provides a reliable sequenced data stream while IP provides the basic building block, the datagram

109 ;;Quote: transporting a datagram is the building block of the Internet; 100 bytes minimum, reasonable reliability, addressing; extremely successful

112 ;;Quote: TCP should have had flow control of both packets and bytes; extra complexity worth the added support for services; e.g., ARPANET

113 ;;Quote: build internets from flows, packet sequences from source to destination; helps resource management and accountability; gateways keep track of soft, flow state
